Abstract: A video signal based on an NTSC system is converted into a signal for EDTV. The converted signal is subjected to signal compression in a signal compression ratio of 910/m times. The compressed signal is added with a pedestal level signal and a side level signal. The combined signal is converted into an analog signal, and thereafter primary color signals R, G and B are generated to be imaged on a high resolution television monitor. Thus, the original video of the NTSC system can accurately be reproduced with respect to a high resolution television monitor with an aspect ratio of 16:9.

Abstract: A biphase-mark coded digital audio signal comprising short and long pulses (IEC 958) is decoded despite substantial variation of sample rate but without a separate synchronization or timing signal and without a phase locked loop. The pulse lengths are measured and then compared with two thresholds. One is a variable threshold which is 1.5 times the average length of the short pulses, this average being stored in a register. This will normally be adequate to discriminate the short and long pulses. The second comparison is with a fixed value which is lower than 1.5 times the pulse length at the highest input frequency. When the comparators disagree irreconcilably in their determination, the resultant of the second comparison is used instead of the first. This allows the system to respond quickly to start-up or sudden change in input data rate.

Abstract: In the document feeder of the invention, the originals stacked in the document hopper always show the same surfaces upward during copy operation. Consequently, when an original document sheet causes paper jam or similar trouble in the transport path, the original may be restacked in the document hopper with the same surface facing upward as that facing upward when the original was first stacked in the document hopper. Consequently an operator is less likely to be confused as to the surface to face upward when stacking originals in the document hopper, resulting in improved operating performance. Further, the structure of installing the original feeding mechanism and the original restacking mechanism separately on both sides of the document hopper and bottom-feed, top-restack configuration of the document hopper simplifies the structure around the document hopper.

Abstract: A communication unit utilizes a caller management unit which monitors in-house lines and detects a caller side calling code included in a calling set up message applied at the time of reference. A control unit stores the detected calling code in one memory region of a memory and reads out the stored calling code from the memory region in response to an output request to produce information corresponding to the calling code. The management unit displays the information produced by the control unit. The memory has another memory region for storing a plurality of predetermined calling codes and caller specification information corresponding to each calling code. The control unit stores the detected calling code into the one memory region in response to a non-response detection to reference by the line monitor.

Abstract: A distortion compensation circuit of a VTR detects distortion of an input ramp signal during a blanking period of a reproduced video signal and compensates the distortion of the entire reproduced video signal. The input ramp signal included in the digital reproduced video signal is compared with a comparison ramp signal equal to a ramp signal to be recorded and the difference thereof can be obtained as a compensation data signal. During the blanking period of the reproduced video signal, the compensation data signal is stored in a compensating memory, using the input ramp signal as an address signal, and during a non-blanking period, the contents of the compensating memory are read out, using the reproduced video signal itself as an address signal. The read compensation data signal is added to the reproduced video signal, whereby distortion of the reproduced video signal is compensated.

Abstract: A technique for producing a cold environment in a refrigerant system in which input fluid from a compressor at a first temperature is introduced into an input channel of the system and is pre-cooled to a second temperature for supply to one of at least two stages of the system, and to a third temperature for supply to another stage thereof. The temperatures at such stages are reduced to fourth and fifth temperatures below the second and third temperatures, respectively. Fluid at the fourth temperature from the one stage is returned through the input channel to the compressor and fluid at the fifth temperature from the other stage is returned to the compressor through an output channel so that pre-cooling of the input fluid to the one stage occurs by regenerative cooling and counterflow cooling and pre-cooling of the input fluid to the other stage occurs primarily by counterflow cooling.
